Abstract

A light-emitting composition containing first and second light-emitting markers. The first light-emitting marker comprises a first light-emitting material and a first binding group configured to bind to a first target analyte. The second light-emitting marker comprises a second light-emitting material which is different from the first light-emitting material and a second binding group which is different from the first binding group and which is configured to bind to a second target analyte. A luminescent lifetime of the first light-emitting material is shorter than a luminescent lifetime of the second light-emitting material. The difference in lifetimes of the first and second light-emitting materials may be used to distinguish between the first and second target analytes in a sample, e.g. by time-gated flow cytometry.

Abstract

This method for producing a positive electrode active material comprises the steps described below. (1) A mixture is obtained by mixing an activation agent which contains one or more alkali metal compounds into an electrode mixture which contains a positive electrode active material, a binder and an electrolyte, and from which at least some of the electrolyte is removed by means of a contact with an electrolyte cleaning solvent. (2) The mixture is heated to a retention temperature that is not less than the melting initiation temperature of the activation agent. (3) The mixture after the step (2) is brought into contact with a liquid that contains water, thereby obtaining a slurry that contains a solid component and a liquid component, and subsequently, the slurry is separated into the solid component and the liquid component. (4) The thus-obtained solid component is exposed to heat and/or a reduced pressure environment, thereby removing water from the solid component, and within 24 hours from the separation of the slurry into the solid component and the liquid component, the ambient pressure at which the solid component is present and/or the temperature of the solid component is changed so that the ratio of the saturated water vapor pressure at the temperature of the solid component to the ambient pressure is 80% or more. (5) The solid component after the step (4) is subjected to a heat treatment at less than 900°C.

Abstract

[Problem] To provide a laminate able to inhibit a color change when white is displayed (color emitted) being strongly felt, even when exposed to the outdoors for a long time. [Solution] This laminate has, in order, a first ultraviolet absorption layer, a first light-absorption anisotropic layer, a second ultraviolet absorption layer, and a second light-absorption anisotropic layer. The first light-absorption anisotropic layer is formed from a composition containing at least one dichroic dye and a liquid crystal compound. The second light-absorption anisotropic layer has an absorption axis in a horizontal direction with respect to a plane of the layer. The first ultraviolet absorption layer and the second ultraviolet absorption layer both satisfy the relationship given in formula (1). The first light-absorption anisotropic layer satisfies the relationship given in formula (2). (1) T(380)≤20; (2) Az>(Ax+Ay)/2; [In formula (1), T(380) represents the transmittance [%] at a wavelength of 380 nm. In formula (2), Ax, Ay, and Az represent an absorbance of linearly polarized light oscillating in the x-axis direction, the y-axis direction, and the z-axis direction, respectively, said absorbance being of a maximum wavelength of absorption of the first light-absorption anisotropic layer in the range of wavelengths of 410-780 nm, inclusive. The x axis is a direction that is parallel to the absorption axis direction of the second light-absorption anisotropic layer in a plane of the first light-absorption anisotropic layer. The y axis is a direction that is orthogonal to the x axis in the plane of the first light-absorption anisotropic layer. The z axis is a direction that is orthogonal to the x axis and the y axis.]
